To all whom it may concern:

Be it known that'I, BIRD A. ROBERTSON, a citizen of the United States, residing at Ben Franklin, in the county ofDelta and State of Texas, have invented a new and usefulBrush-Cylinder for Grins, of which the following is a specification.

y The present "nvention appertains to brushv cylinders for gins, and aims to provide novel and improved means for securing the brush sticks in place and for enabling them to be readily removed and replaced.

The present invention also contemplates the provision of means for holding the brush sticks of the cylinder in place, which will be comparatively simple, non-encumbering and inexpensive in construction, as well as being convenient, practical and eflicient in its use. g p

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment vof the invention, herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention; The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is an end view of thebrush cyl- I inder embodying the present improvements,

portions being broken away. Fig. 2 1s a fragmental plan view of portions of the cylinder.

The brush cylinder includes a cylindrical frame or body 1 which, in practice, usually consists of a plurality of spaced sections or heads, although for the purposes of the prescnt invention, the frame or body 1 may be considered as a unit.

The body or cylinder proper 1 is provided with an annular series of longitudinal grooves or channels 2 in which are snugly seated or fitted, the sticks 3 of the brushes, which sticks 3 are each provided with a longitudinal series of tufts of bristles 4.

In carrying out the present invention, the body or 'cylinderl is equipped at longitudinally spaced points, with transverse grooves or channels 5 between the respective grooves or channels 2. The grooves or depressions 5 are preferably arranged in annular series, and are relatively shallow, while the grooves or. channels 2 are relatively deep. The side walls of the grooves 2, as well as the grooves 5, are preferablv parallel and flat, and the grooves or depressions 5 extend to the side walls of the grooves 2.

The brush sticks or bars 3 are provided along their outer corners or edges with chamfered orbeveled notches 6, which reg ister or coincide with the respective trans verse grooves or channels 5, and the ends of the notches or cut away portions 6 being flush "with the sides of the grooves 5.

Seated or fitted snugly within each of the grooves or channels 5, is a'transversely arranged latch or clamp 7, which is preferjably flush with the periphery of the body or cylinder 1, and which has its ends beveled as at 8, to fit snugly within the respective 4 chamfered or beveled notches '6 of the adjacent brush sticks or bars 3. A screw or other securing member 9 is engaged centrally through each of the latches or clamps 7, and takes into the body or cylinder 1, to hold the latch or clamp tightly in place. The edges of the latches or clamps 7 snugly engage the sides of the grooves 5, to prevent the latches or clamps from rotating or oscillating and the latches or clamps being clamped against the body or cylinder 1, will clamp the brush sticks 8 within their grooves or seats 2, whilethe beveled ends 8 of the latches or clamps 7 in engaging between the ends of the chamfered or beveled notches 6 of the brush sticks, will prevent the brush sticks from sliding or shifting longitudinally within the grooves 2.

In use, the cylinder bearing the brushes and holding or securing members is applied to the gin in the usual manner, as will be evident to those versed in the art. The latches or clamps will effectively hold the brushes in place, to prevent their radial or longitudinal displacement. Should one or more of the brushes become worn out, or

should it be desired to replace one or more of the brushes for any other reason, by

loosening the corresponding latches or clamps 7, the desired brush sticks may be loosened so that they be withdrawn lonor clamps 7 into the respective grooves 5 as above noted. It is to be noted that the clamps or latches 7 when assembled with the body or cylinder and brushes in the manner indicated, will effectively hold the brushes against displacement, and will provide for desirable advantages.

With the present improvement, brushes may be removed and replaced with a minimum expenditure of time and labor. 7

Having thus described the invention,what is claimed as new is 1. In a device of the character described, a cylinder having longitudinal grooves, and having transverse channels between the said grooves, brushes including sticks seated in the said grooves, latches disposed snugly in the said channels and having their ends engaging the brush'sticks to hold them within the grooves, andmeans for clamping the latches within the said channels.

7 2. In a device of the character described, a cylinder having longitudinal relatively deep grooves and transverse rela ively -shallow channels between the grooves, brushes including sticks seated in the said grooves,

Copies of this patent may-be obtained for and having notches coinciding with the ends of the channels, latches fitted snugly within the said channels and having their ends engaging the notches of the brush sticks, and means for clamping the latches within the said channels.

3. In a device of the character described,

a cylinder having longitudinal relatively- S. H. EDWARDS, F. A. CAMERON.
